I don't mean to defend Microsoft in any way shape or form but the RFC is "crystal clear" that a msg-id is not required. Period. The wording leaves no room for interpretation. It's recommended but not required. If the RFC authors wanted it to be required they would have said so. Just because almost all MUA developers programmed their MUAs to generate a msg-id doesn't mean that the sole standard, the RFC that defines our beloved mail format, should be reinterpreted by each admin to fit their personal wishes and desires. Actions like this do nothing but segregate mail systems. Many of the popular web browsers support(ed) the non-standard Netscape and IE HTML tags. That doesn't make those tags official though. Personally I think the msg-id should be assigned by the MTA if for no other reason than for logging and possible authentication purposes. My wishes are part of the RFC though so I'm not going to create a rule that enforces those wishes. My $.02 Justin
